BE'LT- FASTl-IN ER TOOL.

SPECIFICATION forming part of Letters Patent No. 426,942, dated April29, 1890.

Application filed July 27, 1889- $erial No. 318,846. (Morleli) To allwhom, it may concern.-

Be itknown thatl, J OHNLENDBERG, a citizen of the United States, and aresident of Dover, in the county of Morris and State of New J ersey,have invented certain new and useful Improvements in Belt-FasteningMachines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawin gs, and to letters of reference markedthereon, which form a part of this specification.

Figure l of the drawings is a front view. Fig. 2 is a rear View partlybroken away. Fig. 3 is a top plan view; and Figs. 4, 5, and 6 are detailviews.

This invention relates to certain improvements in belt-fasteningpunches; and it consists of the novel construction and combination ofparts, as will appear from the following description and accompanyingillustrations.

In carrying out my invention I employ a handle or frame A, conformed tothe grasp of the hand. Bis a lever, having its fulcrum upon and astridea lateral stud-extension a of said handle, near one end of the latter,being offset and recessed at its fulcrum, as at b and provided with twoupwardly-projecting and slightly-inclined arms I), one standing uponeach side of a closure A said recessed offset receiving said extension.The lever B is acted upon by a spring 13, applied as shown. The long armof the lever B is slightly curved out of alignment with its short armand is flattened outward, its extreme outer end, however, havingguide-studs 1), whose sides or greaterwidths are at right angles to thatof the flat surface of the lever and embrace the outer connecting-pieceof the frame A. The said outer end of the lever B has its edges rangingat right angles to the plane of the guide-studs 1), extended, as atb,forming an extended bearingsurface for said end upon theframe-connecting piece.

The tapered end of the handle or frame A has cast or formed therewithclosures or casings A A having between them, about centrally of theframe or handle A, a narrow opening 0 for the reception of the work orbelt sections. The base and one side of the open ing 0 are extended, asat 0, thus providing thereat an extended right-angle bearing-surface forthe work or belt section to rest against while being operated upon. Inthe side walls of the opening 0 are opposite or facing guideslots 0 thepurpose of which will appear farther on.

C is a plate or carriage, having also a workreceiving opening 0coincident with, but of greater width than, the opening 0, between theclosure A A Said plate or carriage has at one side of its opening (3 aknife edge or cutter 0 the opposite side of said opening serving as afollower C the purpose of which will presently appear.

Connection is effected between the plate or carriage O and the lever Bby a pin d, passing through slightly'curvcd slots 0 in the closure A andsecured to prongs. Upon one side of the closure or casing A is cast apeculiarly shaped chamber or receptacle D, adapted specially for thereception of and to contain the H -form fastening for the belt-sections,such as herein shown. The receptacle or chamber D comprises an outernarrower portion and a base portion, the latter opening at its inner endor bottom into the closure A, and having its outer edge standingslightly away from the closure. The outer or narrow portion of thereceptacle or chamber D consists of central parallel spaced extensions DD of the outer edge of the base or inner portion of said chamber orreceptacle, havin g facing semicircular or concave surfaces.

E is an armed shaft axially supported in studs 6 e, cast upon theclosure A the arm E of which shaft extends into the extended portion ofthe chamber or receptacle D, and has its free end resting or pressingupon the contents of the latter, consisting of aseries of the aforesaidfastenings. The arm E is held under pressure through the action of aspring E encircling the shaft E and secured at one end thereto and atits opposite end to the closure A. The shaftE is conveniently turnedwhen it is desired to elevate its arm E out of the receptacle or chamberD, in order to refill the same by applying suitable pressure to a thumbor finger piece 6*, secured to or formed with said shaft outside of itsbearing-lugs.

F is a slide or bar arranged in the closure A close to the outer sideedge of the follower 0 which normally stands with its inner end aboutflush with the outer edge or surface of the guide-slot C in that side ofthe opening 0. To this slide or bar is connected one end of aslightly-angular lever F, centrally pivoted to the outside of theclosure or casing A, and having its other end provided with a limitingpin or projection f playing in a slot f in the side of the said closureor casin g. The connection between thelever F and the slide F iseffected by means of a pin or projection f 2 on the said slide,extending through a vertical slot f 3 in the side of the closure A, anda slot f in the said lever, which slot extends in the direction of thelength of the lever.

F is a preferably-curved metalplate spring having one end secured to theside of the closure A, its opposite end pressing orbearing upon thelever F near its slide-carrying end, and holding the inner end of theslide or bar F normally about flush with the outer side of theguide-slot c in the closure A.

G is a. thumb-nut gage adjusted in a vertical slot g in one side of thehandle or frame A at one end and near the work-receiving opening 0,which gage has a pointer registering with graduations on said handle.Upon the opposite side of the handle or frame A and having the samerelation with the opening 0 as the gage G is secured a claw-shaped stopG for the work. It will be seen that with the receptacle or chamber Dsupplied with the fastenings and the lapped belt-sections properlyadjusted in place in the openin g c by pressing the lever B against thepressure of its spring the cutter and follower will be simultaneouslyactuated. The cutter will make the required incisions in thebelt-sections, while the follower will be withdrawn suflicientl y fromthe receptacle or chamberD to permit the passage through its bottom of afastening. The lever B being released its spring will automaticallyreturn it to its former or original position, carrying the follower toeject the displaced fastening transversely of the opening 0 through theincisions in the belt-sections, it being guided into and heldtemporarily in the slots 0 by the slide or bar F, after which thebelt-sections are removed and straighten ed, the fastenings being turnedat right angles to their inserted position.

It will be noticed that when the lever B has made its full returnmovement the guide slide or bar F has been retracted to permit the readywithdrawal of the connected belt-sections with the inserted fastening.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. The handle or frame, carrying at one end a simultaneously-actuatedcutter and follower, in combination with a lever to eifect suchactuation of parts, and a receptacle opening into the closure of saidfollower, substantially as set forth.

2. The combination of the handle or frame, carrying at one end acarriage having a cutter and a follower, the closure for said followerand cutter having a work receiving opening, in the side of which areguide-slots or grooves, and the spring-acted-upon lever actuating saidcarriage, substantially as set forth.

3. The combination of the frame or handle, carrying a follower and acutter, and having awork-receiving opening, the sides of which containguide-slots, the spring-acted-upon lover actuating said follower andcutter, and the guide slide or bar actuated by a supplementalspring-pressed lever and the aforesaid lever, substantially as setforth.

4. The combination of the frame or handle having the end closure, thecarriage arranged in said closure, and having a cutter and afollower,the lever for manipulating the said carriage, the receptacle or chamberopening into one of said closures, and the spring-pressed shaft havingan arm pressing upon the contents of said receptacle, substantially asspecified.

In testimony whereof I aflix my signature in presence of two witnesses.
